The shooting took place a little more than one mile away from where the pride parade stepped off earlier in the day.

"After the parade a lot of people just go by Montrose Beach," said witness Kim Shine. "Everyone barbecues out there, vendors sell candy and water bottles, it's just a big gathering around the hill or beach area."

Shine said she heard a sound she thought was fireworks but quickly realized was gunshots.

"We were standing near the top of the hill near Montrose Beach and we heard a few noises," she said. "We didn't know if it was gunshots or fireworks. We just saw a slew of people running toward us."
